Marvel Enterprises has announced a deal that gives Microsoft exclusive rights to make MMORPGs based on Marvel comic book characters for the Xbox 360. This means that no MMORPGs containing Marvel comic book characters will be available for the PC or any non-Microsoft game consoles. A release date for the first title or the amount of titles covered in the deal were unmentioned.

The timing of the deal may be in response to last month's agreement between Sony Online Entertainment and DC Comics for Sony to make a single MMORPG featuring DC Comics characters. Marvel's previous MMORPG history involves a lawsuit against City of Heroes publisher NCsoft last November for allowing players to create characters in the game that closely resemble Marvel comic book characters. The case is yet to be resolved, although many of Marvel's complaints have already been thrown out.
